Abstract: A method for embedding an optical security feature in a digital document with a virtual printer and a security feature service and then sending the digital document to a hardware printer.

Abstract: The present invention relates to a method and system of embedding data in text documents. The method includes obtaining a document having dimensions and at least a first character and a second character and determining a length between the first character and the second character to define an inter-character space. A reference length is determined, where the reference length is a function of the dimensions of the text document. A threshold length is determined, where the threshold length is a minimum length wherein information is not encoded in the inter-character space if the inter-character space is not within the threshold length. The information is encoded into an altered inter-character space wherein a length of the altered inter-character space is an integral multiple of the reference length or a non-integral multiple of the reference length.

Abstract: A method is disclosed to monitor print job status. A list of available printers is determined, and network printers or local printers are determined. The printer status is queried before sending data to a printer. Meta-information is inserted into the print data to know when a document starts to print and when the document finishes printing. The printer is queried regarding status of the print job as well as printer status.
